Chinese dual filings are now linked within DWPI families

09. February 2018

A long-requested enhancement to the Derwent World Patents Index hasnow been implemented – the handling of Chinese dual filings. This is an important development which will mean more efficient and accurate searching.

Since 2009, under Article 9 of the amended Chinese patent law, it has been possible to file for protection with both a utility model patent and an invention patent. This throws up a challenge for the patent searcher, as the dual filed pair of applications are published on different dates and have no obvious link with each other. Therefore, they most often ended up in different patent families with no indication that the utility model has an accompanying invention application and vice versa.

Clarivate Analytics has now devised a unique solution to this problem. Starting with DWPI update 2018/09, a new process for the frontfile combines machine learning with human intellect to identify dual filing pairings and assigns them to the correct patent families within days of publication rather than months as with other sources.

The dual filings identified are paired within the same DWPI family, as in the example below. Note the # symbol identifying the non-convention equivalent utility model.
